WILLIE R. CHAMBERLIN@ OF CHICAGO, UCTS INC., OF WOOSTER, OHIO, A.CORPORATION F OHIO ILLINOIS, ASSIGNORS TO WOOSTER PROD- TRIM'. FOR` WALLCOVERIN'GS Application led December 16, 1931. Serial No. 581,356.

The invention relates to trim members for Wallcoverings and the like,and more particularly to metal trim members of solid cross sectionadapted for use with flexible wall coverings.

Inl the past, metal trim members for similar purposes have includedl anedge-abutting member and a securing flange, and have been constructed ofsheet metal, but these have been found unsatisfactory for severalreasons. l

A serious objection to these sheetmetal members is that they do notpossess 'sufficient rigidity to maintain their shape before or afterinstallation, and after installation j the eXposed portions of themembers are relatively easily dented or bent out of shape,

resulting in an unsightly appearance. A

Another objection to these sheet metal members is that they require afinishing opf eration such as painting or polishing, which operationcannot be satisfactorily done before installation because the finish isapt to 4 become damaged during installation. On the other hand, if thetrim members are finished after installation, the flexible coveringinserted therein is very likely to be damaged during the finishingoperation.

Another difficulty results from the fact that the securing flanges ofthe sheet metal members are of uniform thickness, and form an offsetwith the undersurface to which they are secured. This oset causes acor-` respondingshoulder in the surface of the covering, requiringbuilding up to the covering adjacent the trim member, or cutting away orrabbeting the inner surface of the covering or the undersurface to.which the 'trim member is secured, in order to provide a smooth exterioron the covering. y Accordingly, it is an object of the present inventionto provide a metal trim member of solid cross section'for wall coveringsand the like, having an improved securing flange which will avoid thenecessity for building up tothe covering or rabbeting the /wall orcovering.

Another object is to providea trim member having an edge-abutting andoverlapping portion for gripping and maintaining the covering inposition and at the vsame time presenting a pleasing and ornamental ap,`

f ber which will provide a pleasing and ornamental appearance wheninstalled without rarest@ requiring a lfinishing operation before orafter installation.

These and other objects are accomplished by the improvements comprisingthey present 1nvention which may be stated in general terms asconsisting preferably of an extruded metaltrim member of solid crosssection having an edge-abutting and overlapping portion anda securingflange extendingangularly therefrom, the securing flange tapering from amaximum thickness at the edgeabutting portion to a minimum thickness aits free edge.

Preferred embodiments of the present improvements are illustrated in theaccompanying drawing, in which l Figure 1 is a perspective view of aportion of a room provided with a flexible wall covering, showing therelative positions of the improved trim members;

Fig. 2 is an enlarged fragmentary sectional view through an outsidecorner of the room, as on line 2 2, Fig. l i

. Fig. 3 is an enlarged fragmentary sectional View through an insidecorner, as on line 343, Fig. "1; and

Fig. 4 is an enlarged fragmentary sectional view through the outsideedge of the which extends from the baseboard 15 up'- wardly part way tothe ceiling of the room.

At the outside corner of walls 11 and 12 a trim member 17 is providedfor abutting and overlapping the adjacent edges of the I vided,respectively, at the upper. edges of the covering 16 on. all the Walls,and at the out-K side faces of the`door`jambs 14.

Fach of the improved trim members is preferably of solid cross-sectionand may be of extruded brass or aluminum and the like.

The trim member 17, shown in cross section in Fig. 2, includes a Jpairof intersecting flanges 21a., angularly disposed to each other to formsubstantially a -V j in cross section. An edge-abutting portion 22a,extends outwardly from the apex of the V, and is provided with angularlydisposed surfaces 23@ which are adapted to abut the adjacent edges ofthe coverings 16 on walls 11 and 12.

Each securing flange 21a tapers from a maximum thickness at the apexl ofthe V, or at the edge-abutting portion 22a, to a minimum thickness atits free edge, so that the free edge is substantiallyI sharp. Theundersurfaoe of each flange 21a'is adapted to lie in the plane of theabutting Wall surface, so that the upper surface of the flange inclinesfrom a maximum thickness at the adjacent edge-abutting surface to aminimum thickness at its free edge, and aseries 'of countersunk holesare provided in the flange 21er for attachment to the abutting wall, asby screws24. p

The particular construction of the securing flanges 21a avoids theformation of a corresponding shoulder in the surface of the covering 16,eliminating the necessity of building up-to the covering at the edgeofthe securing flange, or rabbeting the wall or covering.

An edge-overlapping flange 25a prefer ably extends angularly from theedgeabutting portion 22a adjacent each surfacev 23a,

and the undersurface 26a of each flange 25a is substantially parallelwith the outer surface 27a of the corresponding flange 21a, and spacedtherefrom a distance correspondj ing to the thickness ofthe covering 16.The

flanges 25a are adapted to overlap and substantially grip the adjacentedges of the covering 16 on walls 11 and 12, so as to conceal thoseedges and aid inmaintaining the coverings in position. y

Thetrim member 18, which is provided at the inside corner between walls10 and 11, is shown inA cross section in Fig. 3, and includes a pair ofintersecting securing flanges 2lb. The flanges 2lb are angularlydisposed.

to each other to form substantially a V in 'cross section, and the innersurfaces of the Hanges are adapted to lie in the plane of the surfacesof the walls 10 and 11 respectively.

.by screws 24.

remata Each securing flange 2lb tapers from a.

maximum thickness at the edge-abutting portion 22b toa minimum thicknessat its free edge, and is, provided with holes for attachment to thewallskff) and l11 respectively as by screws 24.

The edge-abutting portion 22b is provided with a portion 28 extendingangularly inward from the portion 22?) away from the apex ofthe V, andat an angle to the securing flanges 2lb. The portion 28 is preferablyprovided with angularly projecting edge-overlapping.portions 251) whichoverlap and substantially grip the adjacent edges of the coverings 16 onwalls 1() and 11. The undersurfface 26?) of each portion 25?) issubstantially/parallel with the outer surface 276 of the correspondingflange 2lb,

the other edges are secured by suitable trim )10o members 30.

The trim member 29 is shown in cross section in Fig. 4, and includessecuring flanges 210, disposed in parallel relation to each other andlocated one on themfront face and one on the rear face of the door. Thexinner surfaces of the flanges 210 are adapted to lie in the planes'ofthe front and rear 'faces of the door, respectively.

The trim member 29 preferably includes a covering edge-abutting portion31, which is located around forward edge 32 of the door and extendsbetweenthe flanges 21o.

The portion 31 is provided with an edgeabutting surface 230 adjacenteach securing flange 210, which surfaces are. adapted to abut theforward edges of the covering 16 on the front and rear facesrespectively of the door 14.

Each securing flange 21o tapers, from a maximum thickness at theedge-abutting portion 31 to a minimum thickness at its free edge, and isprovided with a. series of holes for attachment with the door 14, as

Adjacent each edge-abutting surface 230, the edge-abutting portion 31 isprovided with an edge-overlapping flange 250 projecting angularlytl1erefromand the flanges 25e are adapted to overlap and substantially aseries of los y grip the coverings 16 on the front and rear .faces ofthe door.

The under surface 260 of each flange 25e is substantially parallel withthe outer surface 270 of the corresponding securing flange 21a, and ispreferably spaced therefrom a distance corresponding to the thickness ofthe covering 16.

Each ofthe improved trim members above described is of solid crosssection and all of the Walls thereof have sullicint thickness, so thatthe members possess relatively great rigidity and durability.Consequently, the improved trim members will maintain their shape beforeinstallation, and after installation the exposed portions thereof willoffer relatively great resistance to denting or marring of theirappearance.

The vextruding metal trim members possess f an attractive finishedappearance which. is sufficiently durable so as not to be marred duringinstallation. v

In applying a flexible wall covering to a room, the A improved trimmembers are first secured at their proper relative locations by means ofthe screws 24 passing through the respective securing flanges. Thecovering is then cut to proper sizes to fit in the panels bordered bythe trim members. Then the' covering is applied and made to adhere to vthe wall and the outer surfaces of the securing flanges of the trimmembers by means of a suitable adhesive such as glue. The llexibilityofthe covering vis suliicient to permit insertion of the edge portions ofthe covering under the edge-overlapping portions of the trim members.

The im roved trim members each include securing anges which are taperedto a substantially sharpfedge at their free edge portion, so that themarginal edges of the Wall covering or linoleum lay over'the securingvflanges Without causing a shoulder in the covering because of an offsetat the e'dge of necessary tov build up tothe covering at the edge of thesecuring flanges, nor to rabbet either the surface of the wall or theunder-` ness of the covering. Consequently, the

edges of the Wall coverings are concealed to enhance the appearance ofthe finished wall,

and the overlapping flanges securely grip orhold the edge of thecovering yso as to aid the securing -flange. Accordingly, it isnotA Eachofthe improved trim .membersin- We claim:

l. A trim member for Wall coverings and the like including, a'pluralityof angularly disposed securing flanges,- the trim member beingprovidedwith an edge-abutting surface adjacent each securing flange, andan edge-overlapping portion extending angularly from each edge-abuttingsurface, each securing flange having its underside surface in the `planeof the Wall and its upper surface inclined from a maximum thickness atthe adjacent edge abutting surface to ,a minimum thickness at its free`edge, and each edge-overlapping portion having its under surfacesubstantially parallel to the upper surface of the adjacent securingflange.
